LayerZero v2 protocol architecture offers extensive cross-chain interoperability capabilities with three main OApp standards: Omnichain Application (OApp), Omnichain Fungible Token (OFT), and Omnichain Non-Fungible Token (ONFT). It presents various design patterns like ABA, Batch Send, Composed, and Composed ABA for complex interaction scenarios. The protocol aims to solve the interoperability trilemma by separating security and execution layers and providing configurable security levels. This allows the development of secure omnichain applications, potentially reducing liquidity fragmentation and enhancing DeFi ecosystems.
